One of the best things about the Royal Room is its dedication to spotlighting music of world-historical import. This tribute to Miles Davis’s fusion classic, In a Silent Way, is deep in RR owner and supremely versatile keyboardist Wayne Horvitz’s wheelhouse. While Miles’s sly trumpet motifs are obviously integral to the sublimely chill jazz moves here, In a Silent Way is a keyboardist’s paradise, with Herbie Hancock, Joe Zawinul, and Chick Corea flaunting crystalline ambience, rococo ostinatos, aquatic swells, and the suave main theme from “It’s About That Time” on electric piano. There’s much room to improvise here, and Horvitz and his excellent cohorts will surely do this masterpiece justice. by Dave Segal
